Error converting CFML arguments to Java classes for web service invocation.

Question

Hello all.
I am working on writting a small application that will use a web service that is provided by our IVR (Angel.com). I am able to login, however when I attempt to do anything with complex objects, I get the error stated in the title.
It seems to be having a problem with the array, because when I remove it, or turn it into a simple string, i get errors about the function not being found. I am fairly new to web services, and especially dealing with complex data types, so any help would be much appreciated.
You can see my testing page at
http://webservices.fpitesters.com/AngelCalls.cfm
The WSDL I am using can be found at
http://www.angel.com/outbound/wsdl/OutboundCallService.wsdl
Here is sample code that does what I want it to do in Java / Apache Axis

Here is a description of the function I am having problems with
http://www.socialtext.net/ivrwiki/index.cgi?placecall
And attached is my code.
     <cfset email = "xxxxxxxxxxxxxxxxxx">
     <cfset pin = "xxxxxxxxxxxx">
     <cfinvoke webservice="http://www.angel.com/outbound/wsdl/OutboundCallService.wsdl" method="login" returnvariable="login">
          <cfinvokeargument name="email" value="#email#"/>
          <cfinvokeargument name="pin" value="#pin#"/>
     </cfinvoke>
     <cfdump var="#login#">
     <cfset Token = login.getToken()>
     <cfdump var="#token#">
     <cfset CallItem.maxWaitTime = 100>
     <cfset CallItem.phoneNumbers[1] = "7632344306">
     <cfset CallItem.siteNumber = 100041>
     <cfinvoke webservice="http://www.angel.com/outbound/wsdl/OutboundCallService.wsdl" method="placeCall" returnvariable="call">
          <cfinvokeargument name="Token" value="#Token#"/>
          <cfinvokeargument name="CallItem" value="#CallItem#"/>
     </cfinvoke>
     <cfdump var="#call#">

If you are not initializing phoneNumbers as an array before setting
<cfset CallItem.phoneNumbers[1] = "7632344306">
it will be passed as a struct with a key of 1.  This could cause your argument conversion error.
So:
<cfset CallItem.maxWaitTime = 100>
<cfset CallItem.phoneNumbers[1] = "7632344306">
<cfset CallItem.siteNumber = 100041>
Will result in
struct
MAXWAITTIME
100
PHONENUMBERS
struct
1
7632344306
SITENUMBER
100041
<cfset CallItem = StructNew() > <!--- For Good Measure --->
<cfset CallItem.maxWaitTime = 100 >
<cfset CallItem.phoneNumbers = arrayNew(1) /> <!--- Required --->
<cfset CallItem.phoneNumbers[1] = "7632344306">
<cfset CallItem.siteNumber = 100041>
Will result in
struct
MAXWAITTIME
100
PHONENUMBERS
array
1
7632344306
SITENUMBER
100041
